Proton Beam therapy has not been shown to be any more effective for prostate cancer than intensity modulated radiation therapy. IMRT in turn has not been shown to be any more effective than conventional radiation therapy. Both newer technologies should be better – they focus the cell-searing radiation more tightly on the tumor, and should preserve more normal surrounding tissue. However, while the costs are dramatically higher, the clinical evidence of benefit has not yet been demonstrated.

Modern Healthcare reported in 2010 that there were 13 more proton beam therapy centers on the drawing boards for the next few years. (Gated. Harvard Link ) If we invest this capital, it insures that our future costs will climb even higher. Here’s where we really need comparative effectiveness research!
